When I send texts from the web client, they get split even if they are fairly short. I just sent an 80 character text to my girlfriend and it got split. This happens all the time; I think it's been going on for about a year or a little more. It used to work fine before that though.

Attached is a screenshot of it just happening. It's mildly annoying but sometimes people get annoyed because what should be 1 text gets broken up into 3 sometimes.
